Psychometric properties of the Wolpe-Lazarus assertiveness scale

The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were evaluated with a sample of 100 male and 157 female psychiatric patients. There were no significant differences with regard to males and females for total WLAS scores. The WLAS seems to be internally consistent and has acceptable split-half and test-retest reliabilities. A factor analysis performed separately for males and females indicates that the 10 most prominent factors account for about 60% of the accumulated variance. The primary factor, shared by males and females, was labeled General Expressiveness. There was little evidence for the external validity of the WLAS when total scores were correlated with performance on a role play test. However, when WLAS factor scores were evaluated in light of role played performance, somewhat better evidence of the external validity of the WLAS was found in two of the factors for the females.     

Synchronous and desynchronous changes during fear reduction.

The purpose of this experiment, carried out on 27 subjects with intense and circumscribed fears, was to test one main hypothesis and several subsidiary predictions. The prediction that a high-demand in vivo treatment condition produces desynchronous changes and a low-demand treatment condition synchronous changes, was supported by some inter-session findings but not by the intra-session findings. The clear linear relation between heart-rate and reported fear was confirmed, as was the rapid habituation of the heart-rate response to phobic stimulation.The fear-reactions and fear-reductions of psychiatric and non-psychiatric were indistinguishable. High heart-rate responders and low heart-rate responders showed similar patterns of improvement. The constrained laboratory ‘treatment’ procedure used in the experiment produced large and rapid reductions in fear.     

Spatial coding and oblique discrimination by children

Children from five to eight years of age learned to discriminate between mirrorimage oblique lines more readily when cards bearing the obliques were presented vertically than when they were presented horizontally. The difference in performance between the vertical and horizontal planes could not be accounted for by differences in either the external visual context or the availability of asymmetrical body information (e.g., left vs right hand). The superiority of the vertical plane was attributed to the congruence of objective, bodily, and retinal vertical axes for the vertical, but not the horizontal plane, It was concluded, on this basis, that at least part of children's difficulty discriminating between mirror-image obliques is due to their difficulty establishing the internalized vertical axis necessary for the left-right spatial coding of the obliques.     

Semantic knowledge as a determinant of developmental differences in recall

Two experiments examined the possible role of children's semantic knowledge and their ability to encode it in a cued-recall test. Performance of children aged 7, 10, and 13 was observed in encoding specificity tasks, which used homographs as the to-be-remembered words (TBRs).In Experiment I, children of all ages performed better when the output cue words prompted similar meanings to the input cues, than when output and input meanings were incompatible. In Experiment II, all children were required to recall identical items, but younger children, owing to lack of knowledge, were unable to encode pairs comprising input and TBR words incompatibly with output cues. In such circumstances, younger subjects outperformed older subjects. When input and output cues were incompatible for all ages, recall increased with age, possibly due to older childrens' using more effective retrieval strategies.The findings indicate that semantic encoding influenced recall performance at each age. This suggests that age differences in memory are due to differences in the amount of semantic knowledge a child possesses for encoding and cuing and not to capacity differences.     

Competitive behavior: A manifestation of motivation for ability comparison

Social comparison theory predicts that when the person is uncertain about the level of his ability, he may seek comparison information through competitive behavior. This derivation, however, has never been directly tested. An experiment is reported in which the level of the subject's uncertainty about his competence was manipulated and subsequent measures of his competitive motivation and behavior were obtained. The data indicate that higher levels of uncertainty do lead to higher levels of motivation and competition, but only under conditions that minimize threat to self-esteem.     

An empirical test of the covariation analysis in causal attribution

The present investigation was designed to reveal the cognitive inference processes associated with both detection and utilization of covariation information in causal attribution. Male undergraduates were (a) informed that a test was easy or difficult and shown a videotape in which (b) the test-taker's performance was high or low, and (c) covariation between the test-taker's effort expenditure and trial-by-trial outcome was present or absent. High performance was attributed to the test-taker's effort and ability, whereas low performance was attributed to the difficulty of the test. However, recognition of the covariance relationship decreased the attribution of high performance to ability and of low performance to test difficulty and increased the attribution of low performance to effort. Effort attribution in the high performance condition was independent of covariation information. The results are discussed in terms of the relationship between covariation information and typical beliefs about the causes of achievement outcomes.     

Commitment,ego-involvement,and resistance to attack

Subjects with initially extreme or moderate positions (based on a median split) recorded a consonant speech under public, private, or no commitment and later received a strong, mild, or no attack on their position. Extremes were more ego-involved in terms of wider latitudes of rejection, narrower latitudes of non-commitment, and greater resistance to attack, relative to moderates. Commitment had no effect for extremes, suggesting a ceiling effect on changes in the latitudes and resistance to attack for initially high levels of ego-involvement. For moderates, commitment resulted in narrower latitudes of noncommitment, wider latitudes of rejection (greater rejection of discrepant positions), and greater resistance to attack, suggesting that commitment may elevate ego-involvement with the issue. Commitment and ego-involvement may increase the salience of one's attitude position in later situations, thereby increasing the probability of attitudeconsistent behavior.
